67C4023-15N

Overview

The 67C4023-15N is an asynchronous FIFO memory component manufactured by Advanced Micro Devices. It features a 64 x 5 bit configuration, providing uni-directional data buffering capabilities. The device operates at a maximum clock frequency of 15MHz and requires a supply voltage range of 4.5V to 5.5V. Maximum supply current is specified at 45mA. The component is housed in a 20-pin dual in-line package (PDIP).

Feature Summary

• Asynchronous operation for independent read and write clock domains.
• Uni-directional data flow architecture.
• Standard TTL-compatible logic levels.

Applications

• Data buffering between microprocessors and peripheral devices.
• Interface bridging between systems with different clock speeds.
• Digital signal processing data storage.

Procurement Notes

Verify the manufacturer designation as Advanced Micro Devices or AMD. Confirm the specific suffix '15N' indicates the 15MHz speed grade and PDIP package. Ensure RoHS status aligns with project requirements, noting that older variants may not be compliant. Request original datasheets to validate pinout and electrical characteristics against current design specifications.

Selection Notes

Select this component when uni-directional asynchronous buffering is required for small data sets. The 64x5 word depth suits applications needing minimal latency without complex addressing. Verify voltage compatibility with the 4.5V to 5.5V operating range. Consider the 20-PDIP package for through-hole mounting if surface mount options are unavailable.

Part Context

This part belongs to the 67C40xx series of asynchronous FIFOs from Advanced Micro Devices. These components were designed for high-speed data transfer applications prior to the prevalence of integrated SRAM buffers. The series typically offers various depths and widths, with the 67C4023 representing a specific 64x5 configuration optimized for standard logic interfaces.

Replacement Considerations

Check for direct substitutes such as the 67C4023-25N for higher speed requirements. Verify pin compatibility with other 67C40xx family members. Cross-reference with generic asynchronous FIFO equivalents ensuring identical word depth and width specifications.
